A Houston company that's working on a major alternative energy facility in Texas has named two new partners on the project.

Santa Maria Renewable Resources has selected Topsoe as its technology provider, and executed license and engineering agreements, as well as partnered with an engineering firm for its East Texas facility.

The licenses encompass innovations like HydroflexTM and H2bridgeTM technologies. Topsoe’s HydroFlex process layout combined with the H2bridge lower carbon intensity of renewable fuels , and offers greenhouse gas emission savings. The process is part of a sustainable agriculture project currently in development by SMRR in East Texas.

The facility will provide 600 to 700 construction jobs and 300-plus permanent operating employment positions with an expected daily output of up to 3,000 barrels per stream that uses both renewable diesel and sustainable aviation fuel. The demand for RD and SAF grows,and the aviation industry aims to meet net zero carbon emissions by 2050.

SMRR has also partnered with Chemex Global to commence the front-end engineering design for the facility in East Texas.

“The collaboration with Topsoe and Chemex Global marks a significant company milestone, amplifying the potential of our project,” says Pat Sanchez, founder and CEO of SMRR, in a news release. “The incorporation of these licenses, complemented by tailored engineering insights from both organizations will seamlessly integrate into our ongoing front end engineering design. We’re pleased to collaborate with these industry experts ensuring the smooth progression on this project.”

SMRR is a vertically integrated renewable energy, and biobased production developer.

Collaborators from two Houston universities are leading the way in engineering a biomaterial into a scalable, multifunctional material that could potentially replace plastic.

The research was led by Muhammad Maksud Rahman, an assistant professor of mechanical and aerospace engineering at the University of Houston and an adjunct assistant professor of materials science and nanoengineering at Rice University. The team shared its findings in a study in the journal Nature Communications earlier this month. M.A.S.R. Saadi, a doctoral student in material science and nanoengineering at Rice, served as the first author.

The study introduced a biosynthesis technique that aligns bacterial cellulose fibers in real-time, which resulted in robust biopolymer sheets with “exceptional mechanical properties,” according to the researchers.

Biomaterials typically have weaker mechanical properties than their synthetic counterparts. However, the team was able to develop sheets of material with similar strengths to some metals and glasses. And still, the material was foldable and fully biodegradable.

To achieve this, the team developed a rotational bioreactor and utilized fluid motion to guide the bacteria fibers into a consistent alignment, rather than allowing them to align randomly, as they would in nature.

The process also allowed the team to easily integrate nanoscale additives—like graphene, carbon nanotubes and boron nitride—making the sheets stronger and improving the thermal properties.

“This dynamic biosynthesis approach enables the creation of stronger materials with greater functionality,” Saadi said in a release. “The method allows for the easy integration of various nanoscale additives directly into the bacterial cellulose, making it possible to customize material properties for specific applications.”

Ultimately, the scientists at UH and Rice hope this discovery could be used for the “next disposable water bottle,” which would be made by biodegradable biopolymers in bacterial cellulose, an abundant resource on Earth.

Additionally, the team sees applications for the materials in the packaging, breathable textiles, electronics, food and energy sectors.

“We envision these strong, multifunctional and eco-friendly bacterial cellulose sheets becoming ubiquitous, replacing plastics in various industries and helping mitigate environmental damage,” Rahman said the release.
